* Specification of hetters Patent, Pzatggntgd Ja 11g 191% 'Applioation filecl October 28, 1912. Serial No. 728,282.

T all whom it may concern:

Be it known that we, JOHN G. Lnrrnn, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, and ALviN MAT- TIS, a citizen of the United States, residing at Royersford, in the county of Montgomery and State of Pennsylvanimhave invented a new and useful Improvement in Bottleliiahing Machines, of which the following is a specification.

This invention relates generally to bottle making machines, and more particularly to certain improvements upon the bottle making machine shown and described in the application filed October 13, 1911, Serial Number 654,481.

In the machine referred to the bottle finishing tool is carried upon the end of a rotatable spindle, which is forced downwardly and upwardly by means of an arm positively operated, said downward and. up

ward movements taking place at predetermined times and brought about by actuating mechanisms connected with the machine.

In our present invention which pertains more particularly to the finishing tool and actuation thereof, the rotatable spindle is balanced or suspended in mid air and the a predetermined point so as to release the mechamsm and permit the finishing tool to be lowered and actuated at the exact for engaging the bottle neck.

The object of all of these featuresof con point struction and operation is to provide for the accurate and uniform finishing of the bottle neck and compensating for any shortage or surplusage of material in the re-heated neck of the bottle. 1

W'ith thesevarious objects in View, our

Furthermore in the 'pres-' invention consists in the novel features of construction, combination and arrangement of parts all of which Wlll be fully described hereinafter and pointed out in the claims.

in the drawings forming a part of this specification: Figure 1 is a side view of a portion of the bottle finishing machine showing the practical applicationof our inventlon. F 1g. 2 is an enlarged View taken from the oppositeside and showing the locking and releasing mechanisms.

teferring to the drawings A indicates the base of the machine and B the upright stand ard connected thereto, and C the brttle mold which is arranged upon a base C fixed upon a rotatable turret. (Not shown.)

1) indicates the spindle carrying the bot tle finishing tool E at its lower end, the detailsof this tool being more fully described hereinafter. The spindle D has stop collars D and D which respectively limit its downward and upward movements, it bemg understood that ,the spindle passes through bearings rigidly attached to the standard B and this spindle D is rotated back and forth by means of the spindle r0- tating mechanism F arranged upon the top of. the standard 13 and forming the subject matter of an application filed January 12,

1912, Serial-Number 670,887. This spindle i D is suspended or balanced by means of a cable G passing over pulleys G carried by a bracket G bolted to the standard 13, said cable having a weight or weights G attached to the end thereof, said weight being justsutticient to maintain the spindle and attached tool in a balanced or floating condition.

It will be understood that any suitable swivel connection may be employed to connect the cable to the top of the spindle so as to permit said spindle to be rotated during its up and down movements.

Thefinishing tool Ecomprises the plug E at the lower end and the arms E carrying the jaws E which cooperate with the plug E to produce the desired shape of bottle neck.

The arms E are pivoted at E to a casting E attached to the spindle and at their upper ends :are united by means of a spring E". ltach arm E carries a supplemental arm 13, which is provided with frictional rollers E at its upper end and an adjusting screw E at its lower end. These supplemental arms E. are adapted to be engaged a sliding collar H movable upon the spindle, the lower end thereof beingtapered, conical or'wedgeshaped as shown at H so-that as the'collar forced down upon the spindle the tag pered end passing vbetween the armsE will readily expand them carrying with them the arms E and bringing the jaws, E inwardly upon the neck of the bottle,the plug E having entered the neck of the bottle as the jaws E are being forced inwardly. Any further movement of the collar H after I passing the inclined portion H will have no effect upon the jaws so far as their separation is concerned for the reason that the. upper portionoi the collar H is of uniform diameteix The frictional engagement of the tapered or inclined portion of the collar H with the arms lil is surficient to cause the spinning tool and spindle to be lowered inasmuch as they are suspended in a balanced condition and consequently the slight downward pressure applied thereon during the expanding operation is suiiicient to carry these elements downwardly. a I For the purpose of moving the collar H downwardly we employ an arm I which is I mounted upon the end ota short shaft 1 journaled in a bearin formed in the standard B and a second arm K is'alsofrigidly attached to this short'shaft'l and'movesiii unison with the arm l. and attached tosaid arm Ii is a weight K which is slightly greater than the weight G so that when the arm I is released the weight K will be sutlL cient to carry the arms Kand l downwardly overcoming thecounter-balance G and causing the spindle and tool to move downwardly, the free end of the arm I being bifurcated and engaging the grooved upper end of the collar H. I

For-the purpose of holding the arm I in an inoperative position we employ a locking lever L pivoted at L to the standard B, the upper end of said lever'being held against a stop pin L by means of a spring L con nected to the standard and when in this position the upper end of the'stop lever L engages a plate or block M clamped or otherwise-secured to the arml and it is obvious thatso long as the'upper end of the lever L rests beneath this block M the arm I cannot descend.

For the purpose of tripping or releasing the locking lever I, we employ a's'triker lug or pin,N,-which is fixed to the mold base at such a point thatas themoldmoves around beneath the finishing tool this striker pin or lug N will engage the lower end of the lever Lythrowing theupper endout of eng avement with the block- M andthe weightK immediately acts to set the arms K and-I descending; carrying with them finishing tool and spindle. these parts being shown in this, positionin Fig. 2 ofthe drawin As the inventi on.

finishing tool descends the thereof engage the re-h'eated neck of the bottle and being rotated first in one directionand then in the other the neck or the bottle is properly and accurately shaped. consequently the arm I are returned to their normal position orupper positions by means of a pitman T? operated by the cam wheel P and it will be noted that the upper end of this pit-man P is formed with an open crotch in which rests the pin K carried at the end of the arm is and a coil spring it? serves to keep" these" parts in" engagement. By means of this construction it is obv ous that the pitman l can have a downward movement independent-of the movement of the arm l t, for if the striker pin or lug N should for any reason tail to engage the lower end of the locking lever L. said lever will remain in engagement with the arm I and hold the same elei-ated thereby preventing the finishhold the same inoperative at all other times. By means of the set screws E relative move-v ment of the arms E can be regulated.

When the arm K is lifted by the pitman P. the spindle and finishing tool will be carried up at the same time thereby lifting the finishing tcol clear of the finished bottle.

neck, and the first portion of the upper movement of the arm I will oi course be to release and separate the 1aws'E and the continued upward movement will completely remove the finishing tool from the neck of the bottle. read for the next operation. It will alsobe understood that the moment the arm I is lifted a suilicient distancethe spring The arm Kand- L will draw the locking lever backso as to throw its upper end into engagement with theblock N clamped to the side of the arm I.

It will of course be understood-that the details of ourstructure may be chan ed or varied to suit various circumstances without departing from the broad principle of our 'lVhat we claim isz- 1.v A device of thekind described com prising I a counterbalanced spindle carrying afinishingtool at its lower end. gravity operated means for lowering said spindle and tool together with gravity operated means for raising saidspindle to its normal position. a t 1 I 2.
